Title: Method of controlling the quality of tobacco raw material while receiving
Inventor: HONCHARUK VOLODYMYR YAKOVYCH
Filed: 2000-04-28
Abstract: A method for controlling the quality of tobacco raw material while receiving is used in tobacco industry. Spot samples are taken from a tobacco lot (in bales or piles) by one bunch of leaves from three places according to the diagonal of each bale or pile of the lot. The spot samples of leaves from each bale or pile are put together, a combined sample is formed, it is divided into three parts. Оne part of leaves is used to determine the moisture content, аnd the second part to determine the impurity content. The third part is used for chemical investigations. The moisture and impurity content of the tobacco raw material are determined using weighing methods. An analytical sample of the tobacco raw material chopped is treated by a mixture of acetone with hexane (2:1) while mixing for 30-50 minutes, the liquid phase is quantitatively separated from the solid phase and evaporated until dry, the dry residual is treated 2-4 times with a solution of sodium hydrocarbonate, the solutions obtained are combined, acidified with concentrated hydrochloric acid up to pH l-2 and stirred up 2-4 times with benzol, the combined benzol еxtracts are dried by anhydrous sodium sulfate and evaporated in a flask until dry, 2-5 ml of methylating reagent are added to the solid residual and are kept 10-15 minutes on boiling bain-marie, while connecting the the flask to a backflow condenser, then the flask is cooled, water 1-2 ml and hexane 1-2 ml are added and it is shaken, then organic phase 1-2 microliters is added to an evaporator of the chromatograph with the aid of a microsyringe and it is chromatographed. According to the chromatogram the content of -naphthylacetic acid (-NAA) in the tobacco raw material is calculated and a conclusion is made as to the appropriateness of the tobacco raw material for making tobacco goods.
